Honcho Python SDK Migration (v1.6.0 → v2.0.0)

Overview

This skill migrates code from honcho Python SDK v1.6.0 to v2.0.0 (required for Honcho 3.0.0+).

Key breaking changes:

• AsyncHoncho/AsyncPeer/AsyncSession removed → use .aio accessor
• "Observation" → "Conclusion" terminology
• Representation class removed (returns str now)
• get_config/set_config → get_configuration/set_configuration
• Streaming via chat_stream() instead of chat(stream=True)
• poll_deriver_status() removed
• .core property removed

Quick Migration

1. Update async architecture

# Before
from honcho import AsyncHoncho, AsyncPeer, AsyncSession

async_client = AsyncHoncho()
peer = await async_client.peer("user-123")
response = await peer.chat("query")

# After
from honcho import Honcho

client = Honcho()
peer = await client.aio.peer("user-123")
response = await peer.aio.chat("query")

# Async iteration
async for p in client.aio.peers():
    print(p.id)

2. Replace observations with conclusions

# Before
from honcho import Observation, ObservationScope, AsyncObservationScope

scope = peer.observations
scope = peer.observations_of("other-peer")
rep = scope.get_representation()

# After
from honcho import Conclusion, ConclusionScope, ConclusionScopeAio

scope = peer.conclusions
scope = peer.conclusions_of("other-peer")
rep = scope.representation()  # Returns str

3. Update representation handling

# Before
from honcho import Representation, ExplicitObservation, DeductiveObservation

rep: Representation = peer.working_rep()
print(rep.explicit)
print(rep.deductive)
if rep.is_empty():
    print("No observations")

# After
rep: str = peer.representation()
print(rep)  # Just a string now
if not rep:
    print("No conclusions")

4. Rename configuration methods

# Before
config = peer.get_config()
peer.set_config({"observe_me": False})
session.get_config()
client.get_config()

# After
from honcho.api_types import PeerConfig, SessionConfiguration, WorkspaceConfiguration

config = peer.get_configuration()
peer.set_configuration(PeerConfig(observe_me=False))
session.get_configuration()
client.get_configuration()

5. Update method names

# Before
peer.working_rep()
peer.get_context()
peer.get_sessions()
session.get_context()
session.get_summaries()
session.get_messages()
session.get_peers()
session.get_peer_config()
client.get_peers()
client.get_sessions()
client.get_workspaces()

# After
peer.representation()
peer.context()
peer.sessions()
session.context()
session.summaries()
session.messages()
session.peers()
session.get_peer_configuration()
client.peers()
client.sessions()
client.workspaces()

6. Update streaming

# Before
response = peer.chat("query", stream=True)
for chunk in response:
    print(chunk, end="")

# After
stream = peer.chat_stream("query")
for chunk in stream:
    print(chunk, end="")

7. Update queue status (formerly deriver)

# Before
from honcho_core.types import DeriverStatus

status = client.get_deriver_status()
status = client.poll_deriver_status(timeout=300.0)  # Removed!

# After
from honcho.api_types import QueueStatusResponse

status = client.queue_status()
# poll_deriver_status removed - implement polling manually if needed

8. Update representation parameters

# Before
rep = peer.working_rep(
    include_most_derived=True,
    max_observations=50
)

# After
rep = peer.representation(
    include_most_frequent=True,
    max_conclusions=50
)

9. Move update_message to session

# Before
updated = client.update_message(message=msg, metadata={"key": "value"}, session="sess-id")

# After
updated = session.update_message(message=msg, metadata={"key": "value"})

10. Update card() return type

# Before
card: str = peer.card()  # Returns str

# After
card: list[str] | None = peer.card()  # Returns list[str] | None
if card:
    print("\n".join(card))
